· The bio-based content of the new polyurethane dispersion product is about one-third.
To combat climate change, the chemical industry needs to gradually move away from petroleum and other fossil raw materials and towards renewable raw materials. As a result, Covestro is increasingly using alternative raw materials, including biomass feedstocks. For example, the company has now launched a new aliphatic polycarbon polyether copolyurethane dispersion for textile coatings, Impranil CQ DLU, with approximately 34% of the carbon content coming from plants. The launch of the pure petroleum-based version of Impranil DLU has been very popular with customers, and the launch of Impranil CQ DLU expands Covestro's portfolio of some of its current bio-based dispersions for textile coatings.
Covestro has launched a new partially bio-based waterborne polyurethane dispersion called Impranil CQ DLU for automotive interiors and other applications from Covestro.
The new product offers the same excellent performance as Impranil DLU with a high solids content of 55%. As a result, customers can now easily improve the sustainability of their textile coatings by replacing Impranil DLU with IMPRANIL CQ DLU on a one-to-one basis during processing. Sustainability is of paramount importance to the chemical industry, brands and consumers, and is increasingly becoming a decisive purchasing factor. CQ stands for "Circular Intelligence" in the new product name and is designed to identify Covestro products that contain at least 25% alternative raw materials.
As a raw material for Insqin's technology, the existing Impranil DLU has been able to coat waterborne textiles without the use of solvents. The carbon footprint of this coating is significantly lower than that of solvent-based systems. Dr. Torsten Pohl, Global Head of Textile Coatings at Covestro, said: "With the innovative Impranil CQ DLU becoming part of our Impranil CQ portfolio, the textile coatings industry is now able to use more renewable resources and take a step closer to becoming more sustainable. ”
Impranil CQ DLU can be used to produce synthetics for products such as sporting goods, technical textiles, automotive interiors and luggage. Textile coatings based on the new high-performance dispersions offer excellent hydrolysis resistance, extremely high lightfastness, as well as high tensile strength and scratch resistance. In addition, the textile coating has a pleasant touch and good alkali resistance. Impranil CQ DLU can be used for both intermediate coats and top coats, and is suitable for a variety of processes, including direct coating, transfer coating, printing, and microfiber impregnation.
